solve the inequality -3/10x -7 < 1/2
Step-by-step explanation:
-3/10x=1/2+7
=15/2
x=15/2×10/-3=-25
-25<1/2
Difference between they both was
1/2-(-25)
1/2+(25)
=51/2
=25.5

The second H-shaped polygon is a scaled copy of the first. The height of the original H is 5 units. The width is 10. The center bar is 4 across. The height of the copy is about 1.25 units. The width is about 2.5. The center bar is 1 across. Show one pair of corresponding points and two pairs of corresponding sides in the original polygon and its copy. Consider using colored pencils to highlight corresponding parts or labeling some of the vertices. What scale factor takes the original polygon to its smaller copy? Explain or show your reasoning.
Answer:
a. See attachment 2
b. Scale factor is 1/4
Step-by-step explanation:
See attachment 1 for complete question
Given
Original
[tex]Height = 5[/tex]
[tex]Width = 10[/tex]
[tex]Center = 4[/tex]
Scaled Copy
[tex]Height = 1.25[/tex]
[tex]Width = 2.5[/tex]
[tex]Center = 1[/tex]
Solving (a): Corresponding Points & Sides
The corresponding points of the original copy to the scaled copy can be gotten by writing out the measurements as : (x,y)
Where x represents the original and y represents the scaled copy
Taking the height as a point
We have:
[tex]Height: (5,1.25)[/tex]
This will be represented as a dot or point.
A dot at the tip of the line representing height in the original and scaled copy can be colored green
And the width and center as sides
We have:
[tex]Width: (10,2.5)[/tex]
[tex]Center = (4,1)[/tex]
These will be represented by lines
For width:
Two lines representing width in the original and scaled copy respectively can be colored yellow
For center:
Two lines representing center in the original and scaled copy respectively can be colored red
See attachment
Solving (b): The scale factor
To solve for the scale factor, we simply divide the measurement of the scaled copy by the original copy
Recall that:
[tex]Height: (5,1.25)[/tex] , [tex]Width: (10,2.5)[/tex] and [tex]Center = (4,1)[/tex]
Using Height:
[tex]Scale\ Factor = \frac{1.25}{5}[/tex]
This gives:
[tex]Scale\ Factor = \frac{1}{4}[/tex]
For width:
[tex]Scale\ Factor = \frac{2.5}{10}[/tex]
This gives:
[tex]Scale\ Factor = \frac{1}{4}[/tex]
For the center:
[tex]Scale\ Factor = \frac{1}{4}[/tex]
Hence, the scale factor is 1/4
Stacy was sitting in a seat at a football game when another ticket holder told her she was in the wrong seat. The other ticket holder politely told Stacy she needed to go 2 rows up and 4 seats to the left. Which rule describes the translation needed to put Stacy in the correct seat?
1. (x, y)--->(x – 4, y + 2)
2. (x, y)--->(x – 2, y + 4)
3. (x, y)--->(x + 4, y – 2)
4. (x, y)--->(x + 2, y – 4)
Answer:
1
Step-by-step explanation:
So it has to be positive 2 because its going up not down and its going left making it negative 4 and up is the y value and left is the x value

find two numbers whose sum is 27 and product is 365
Answer:
There are no real number solutions to this.
Step-by-step explanation:
x + y = 27
xy = 365
y = 365/x
x + 365/x = 27
x^2 + 365 = 27x
x^2 - 27x + 365 = 0
x = [27 +/- sqrt(27^2 - 4 * 1 * 365)] / 2
x = (27 +/- sqrt (-731)/2
- No real roots.
The total bill of a meal at a restaurant is 25x-115. Five friends agree to split the cost of the meal equally. What could you do to find the amount that each person must pay? Explain.
Answer:
Sample response: Factor the GCF of five out of the total bill. Divide both terms of the expression by 5. The result is 5x – 23, which is the expression that can be used to find the amount each person pays.

If the point of the preimage is (5,2) and the point of the image is (1,2), what RULE was applied to the preimage to obtain the image?
A) (x, y + 4)
B) (x + 4, y)
C) (x - 4, y)
D) (x, y - 4)
Explanation:
We have x = 5 turn into x = 1. We need to subtract 4 from the x coordinate to get this. Therefore x turns into x-4.
The y coordinate stays at y = 2 the entire time, so y isn't altered. We have y map to y.
Overall, the rule is [tex](x,y) \to (x-4, y)[/tex] which translates the point 4 units to the left.

Louise bought a frame and canvas online for $125. Then she bought all the supplies shown in the table and paid a 7% sales tax on the supplies
only.
Item
Cost ($)
Brushes
12.50
Paint
19.50
She took the amount that she spent on the canvas, frame, and supplies, and marked up the price by 115%. How much did she charge for her
painting? Round to the nearest cent.
9514 1404 393
Answer:
$342.37
Step-by-step explanation:
When a quantity is marked up by x%, its marked-up price is (1 +x/100) times its original price. Tax is effectively a markup.
Louise's costs are ...
$125 + (12.50 +19.50)(1.07) = $159.24
Louise priced her painting at ...
$159.24·(1 +1.15) = $342.37
Savannah drew a map of Texas for her Geography class. According to Savannah’s map scale, one-half inch on the map represents approximately 77.5 kilometers. If the actual distance from Austin to El Paso is approximately 930 kilometers, what is the approximate distance between Austin and El Paso on Savannah’s map?
Answer:
6 inches
Step-by-step explanation:
First, take the 930 kilometers and divide it by 77.5 kilometers. You will get 12. This means the distance between Austin and El Paso is 12 one half inches. That is equivalent to 6 inches.

The minute hand of a clock is 1.4 centimeters long. How far does the tip of the minute hand travel in 40 minutes? (Round your answer to two decimal places.)
Answer:
2.93cm
Step-by-step explanation:
I have to admit, this stumped me but I got o work and here's what I have for you. Hope this helps. TIP: remember it is the minute hand not any other hand.
For this one you will have to find the circumference of the clock because as the min hand goes round and round, it will act as a radius and it will go in a circular motion.
Formula will be π2r= 3.l4 * 2 * 1.4cm=8.792cm per every one revolution of the minute hand. Remembering that for the minute hand to revolve round the clock it has to cover 1 hr = 60min. For you to get the total circumference,
you'll have to take 8.792cm but since it is per every one revolution of the minute hand, multiply it by 40/60min. The answer will be 2.93066cm before rounding off. After rounding off you will have 2.93cm. Quite lengthy but I assure you after practicing you'll have at your fingertips.
Translate this phrase into an algebraic expression. 63 decreased by twice Carlos's height Use the variable c to represent Carlos's height.
Answer:
63-2c
Step-by-step explanation:
You write 63 and substitute decreased with a subtraction sign. Twice means to multiple by 2. so for twice of Carlo's height you would write 2c.

The bakers at Healthy Bakery can make 350 bagels in 5 hours. How many bagels can they bake in 20 hours? What was that rate per hour? SHOW WORK, ITS RATIOS!!
Step-by-step explanation:
It is given that,
The bakers at Healthy Bakery can make 350 bagels in 5 hours.
We need to find how many bagels can they bake in 20 hours.
In 5 hour = 350 bagel
In 1 hour = 70 bagel
To find no of bagel in 20 hours, multiply 20 by 70 as follows :
In 20 hours = 70×20
= 1400 bagels
So, 1400 bagels can they bake in 20 hours. Also, the rate per hour is 70 bagel/hour.

You must use 2 eggs to make 6 dozen cookies. How many eggs are needed to make 42 dozen
cookies? Use a proportion to solve.
Answer:
14 eggs
Step-by-step explanation:
Answer: It takes 14 eggs to make 42 dozen cookies
Step-by-step explanation: To solve using a proportion first start out with 2eggs/6cookies (They are in a dozen but 42 is also in a dozen so it cancels out). Now that you have 2/6 you now have to find the x in x/42. 42 divided by 6 is 7 so multiply 2 by 7 and you get: It takes 14 eggs to make 42 dozen cookies or 14/42. Hope this helps
